Looking for a tough, drought-tolerant shrub that brings both beauty and ecological benefits to your southwestern garden? Meet the smoothpod hoarypea (Tephrosia leiocarpa), a charming native plant that’s perfectly adapted to the challenging conditions of the American Southwest.
What Makes Smoothpod Hoarypea Special?
This perennial shrub is a true desert survivor, sporting attractive silvery-green compound leaves and clusters of purple-pink pea-like flowers that appear throughout the growing season.
